False promises on delivery and collection dates

Twice this year I have bought items on takealot. Arrives after the promised date and then being defective and needing to return /need to return as per free 30 day option, they never collect on promised day only for me to follow up with them to get a new date which is also missed to have to follow up AGAIN. Reason for using takealot and not retail stores is to avoid useless service but that's all I seem to run into now with them...
